Hi Guys

What Compressor 3 MP4 settings should I choose for a 10 min 9GB QT video (exported from FCP) to be uploaded onto a website?

Client said 'I've been trying to upload the video to our website but our IT contact has told me that it is too big. Could you send the file in MP4 format compressed for web?'

To clarify, the video is not intended for YouTube. Rather, it is to be placed directly onto the Client's website by them.

Any thoughts would be really appreciated.

Warm regards

Peter

You do not want to use Compressor 3 for MP4. Compressor 3 can not encode to H.264 MP4. It can encode the H.264 .mov or, using iOS preset H.264 .m4v which you can change to .mp4 but you have no control over the settings.

"Too big" is a bit vague. You need to include information about the frame size and content (fast motion, talking heads, etc) to have some idea of what the data rate should be.

What Compressor 3.5.3 MP4 settings should I choose for a 10 min 9GB QT video (exported from FCP) to be uploaded onto a website?

Thanks so much for replying Craig. I've only ever encoded videos for YouTube or DVD so this is new for me.

It's 1920 x 1080 QT FCP Export from a standard ProRes 422 Sequence.

Content wise - fixed shots of talking heads mostly, static shots of software, static wide shots of people in a classroom.

10mins 25secs running time.

Actually, it's Compressor 3.5.3 I have (the one with 'Final Cut Studio') - silly me. Does that make any difference?

I came across this tutorial http://www.kylegilman.net/2011/02/25/making-mp4-h-264-videos-in-apple-compr... "Making MP4 H.264 Videos in Apple Compressor" from February 25th, 2011.

[peter dunphy] "I've only ever encoded videos for YouTube"

When encoding for YouTube you'd of course be using a much higher data rate since they'd be compressing it again. In this case you'll be doing it directly.

[peter dunphy] "Actually, it's Compressor 3.5.3 I have (the one with 'Final Cut Studio') - silly me. Does that make any difference?
"


No difference. Compressor 3.x does not do H.264 .mp4.
The new Compressor 4 does do H.264 .mp4
Ironically Quicktime Pro 7 has been able to do H.264 .mp4 for some time, just not Compressor until Compressor 4 arrived.

If you want to know what YouTube would do (they do a pretty good job) find a similarish video at 1920x1080 and download it and look at the data in MediaInfo. You must download the file without encoding or converting though.

Safari does this easily. Play the YouTube video you want at 1920x1080. Go to Window/Activity in Safari. When you get the Activity list look for the file that's much larger than the rest and growing. Click on that and it should download.

Of course you may find the data rate you'd need for a 1920x1080 video a bit high for your viewers. You might consider 1280x720 instead. You'd have to have a good idea of the internet connection speed and computer capabilities of their computers. That's why some offer several sizes, just as YouTube does.

This article is old (about two years old now) and doesn't include 1920x1080 but it does tell you what Jan Ozer found for 1280x720 files on YouTube. It may have changed in two years though. Do your own investigation. Also note that at similar data rates your file would look better because YouTube's is compressing an already compressed file.

This article mentions what YouTube does with 1080.

BTW, if your source is 1080i instead of 1080p, don't forget to deinterlace.

HI Craig

Thanks so much for your highly informative posts. Is there any software freely available (even a demo of something) I could use instead of Compressor?

[peter dunphy] "Thanks so much for your highly informative posts. Is there any software freely available (even a demo of something) I could use instead of Compressor?"

Sure, MPEGStreamclip is free and does H.264 .mp4. Some people like Handbreak but I'm partial to MPEGStreamclip. Handbreak is certainly worth a try because it uses a better H.264 codec though (X264). I've bumped into occasional compatibility issues with it though.

Excellent, thanks Craig, I will absorb all the info you gave me and give MPEG Streamclip a whirl for now. Will post back with how I get on. Fingers crossed :o)

Hi Craig

Once in the "MPEG Streamclip - MPEG-4 Exporter" should I choose 'Compression: H.264' or 'Compression: Apple MPEG4 Compressor'?

H.264. The other one is much like the older not good one that Compressor 3 uses.

I found a similar video on YouTube (http://www.youtube.com/watch?v=ip0P3xs9TSw) and when downloading the file, the info in Window > Activity showed a data rate which varied between 350 - 625 KB/sec.

Should I then input a similar data rate into MPEG Streamclip?

I'm guessing that in MPEG Streamclip I should tick the Limit Data Rate box and input a maximum data rate. In this case it would be 625 KB/ sec.

How does this sound? It's a video for a UK website, by the way.

[peter dunphy] "Activity showed a data rate which varied between 350 - 625 KB/sec. "

That's your download data rate. You have to open the file in Quicktime or, better still, MediaInfo and look at the file's data rate.

Download the Mac version with GUI.

Thanks again Craig

The GUI for the similar video I downloaded from YouTube shows:

Video
710 Kbps, 640 *360 (16:9) at 29.970 fps. AVC (Main@L3.0) (CABAC / 3 Ref Frames)

Audio

129 Kbps, 44.1 KHz, 2 channels, AAC (LC)

So, I'm thinking now that I should limit my data rate to 710 Kbps. Would that be right?

Here is the video I will be compressing



However, I'm using the original 9GB version of it to compress (not this YouTube version)

[peter dunphy] "So, I'm thinking now that I should limit my data rate to 710 Kbps. Would that be right?"

That would be reasonable for video at 640x360.


[peter dunphy] "129 Kbps, 44.1 KHz, 2 channels, AAC (LC)
"


As well as this although you'd be targeting 128kbps. Sometimes there's a little overshoot or undershoot when encoding

It was probably set at 700kbps for video and 128kbps for audio.
That's 828kbps overall.

[peter dunphy] "(Main@L3.0) (CABAC / 3 Ref Frames)"

In some professional compression software you'd be able to set this as well. CABAC can improve quality a little bit. A program like Telestream Episode would allow you to set this.

Hi Craig,

Thanks for the information.

Due to feeling like I'm 'stabbing in the dark' I've written back to them with the following:

'Can your IT contact please confirm the following:

1. What ratio is the compressed MP4 required in? (Currently at 1920 x 1080)
 
2. What data rates limits are required for video and sound? (e.g. video data limit of 1 Mbps, 128kbps for audio)

3. What is the maximum file size allowed for the compressed MP4?'

If they only want the video in a smallish box then that will no doubt use less data than a video that has to fill full-screen and remain clear of artifacts.

Will post again once I hear back.

Good questions. It's important to ask clients things like this.
You'll find out whether they really understand and know what they're asking for and, if not, they will then entrust you, if they don't, rather than second guess you afterwards.

Hi Craig

I received the below from the tech department of the client. If you can offer any advice whatsoever I'd really appreciate it:

"I downloaded the video from the website yesterday. The video seems to have an interlacing problem. This is nothing to do with compression (necessary to keep the download size manageable).

You can see it in the attached screenshots; any time there is movement, a series of jagged horizontal lines appear around the movement. This is quite apparent in the close-ups of interviewee speaking.

I believe the video should have been interlaced before it was supplied to us. Interlaced footage is designed for web delivery; de-interlaced footage as seen here is only used for TV broadcast and DVDs."

The video was shot at 50i on a Canon XHA1 (PAL) in the UK then edited as ProRes 422, exported as Quicktime from FCP, then brought into MPEG Streamclip.

Using MPEG Streamclip I created a compressed MP4 with the following stream info:

Duration: 0:10:24
Data Size: 89.98 MB
Bit Rate: 1.21 Mbps

Video Tracks:
H.264, 640 × 360, 25 fps, 1.08 Mbps

Audio Tracks:
MPEG-4 Audio stereo, 48 kHz, 128 kbps

Under the MPEG Streamclip heading 'Deselect for progressive movies' I had 'Interlaced Scaling' ticked (yes), 'Reinterlace Chroma' ticked (yes, greyed out) and 'Deinterlace Video' not* ticked (no). Field Dominance is set to Upper Field First.

I'm pretty confused since I had 'Interlaced Scaling' ticked.

What do you think please?

Warm regards

Peter

The client had shown me a 'testimonial' page on their website which showed videos at 640 × 360. Small little boxes. They asked me to copy that, so I compressed the video to 640 × 360. To me, in the small 640 × 360 box, the video looks good and comes in within the 100MB data limit they wanted.

It was only once I'd delivered the compressed MP4 at 640 × 360 that they uploaded the video directly to their website. However, for my video (not the previous testimonial videos) they included a 'Download' option. Now, when they expand the video to view any bigger that the 640 × 360 small box they'd requested from me, the video image looks jagged.

Do you think this is less about interlacing and perhaps more about the less-than-100MB data limit the client wanted for the video?

Update - by ticking 'Deinterlace Video' (Interlaced Scaling and Reinterlace Chroma greyed out and ticked) the 'jagged edges' seem to go away. Does this sound normal?
