Size of mp4 for 60 minute video? (720p)
on May 2, 2017 at 3:00:25 pm

Hi folks,

I'm working on a project using SVP12 which will result in a 60 minute video (approximate ). This .mp4 file will be copied onto hundreds of USB sticks for sale/distribution.

I have 4 questions:

1. Which render template should I use to ensure the best render?
2. How large will this file be?
3. Would a 4GB USB stick suffice?
4. Is there a way to calculate the file's size given the 720p and video length?

As you can see... I need to be absolutely certain that the sticks we're purchasing in advance will have sufficient capacity.

Thanks in advance for any advice.
Gilles

As a rough starting point for your research, the higher the BITRATE the larger the file. What you haven't said is what/where the File will be played on and shown monitor.

720p simply indicates one of the dimensions of the Frame and that it will be Progressive.

Being helpful here, why not try a suck n see attitude? I've calculated MPG for DVDs using a BitRate calculator, must be one for MP4s?

Does any of this help?

Thanks Graham, I appreciate your input.

It will be mainly displayed using home computers. Getting answers to my four questions will greatly help me in figuring this out. I'm happy to try but having prior knowledge will help with efficiency. At this point I lack data, hence my specific question ☺

Cheers,
Gilles

Maybe just render out 6 minutes, see what size it is then multiply by 10 to get an idea of flash memory size. Take more than one 6 minute sample if necessary. 20mb/s is a good starting point for good enough quality.

Also be careful with filesize limits. A new pendrive is most probably factory formatted to fat32, which can't hold files bigger than 4GB, even if the drive itself is 16 or 32 GB...
You can of course format to exfat, which does not have this limit.
Just be aware.
20Mbps for 60 minutes will result approximately 9GB (plus the audio!), so for that you'll need 16GB drives, or lower bitrate to 14Mbps, so a 8GB drive seems to be enough (and almost full).
For 720p 14Mbps is still qutie good, I think.

Best regards

Thanks John!
I'll wait and see if someone else pipes in.
Surely someone must know the answer to my 4 questions :).... I didn't think the questions were arcane lol. The answers will also likely help others.

Gilles, I use Handbrake when rendering 1920 x1080 files and got just under 2 hr videos down to under 5 gigs so no problem getting 1 hr to under 4 gigs. Hope that helps.
Don't forget to format the USB sticks in NTFS to overcome the size limit.

Forgot to mention that I use the Internet AVC/AAC 1920 x1080 preset. Adjust as needed for your requirements.

Hey Mike!
Great to see you again!

Thanks for your 2 posts. very helpful.

So the "Internet" setting is of good quality...not only for "internet purposes" only?

... and 8000-16000 Mbps will suffice? (this is the default setting for the Internet 720p template)

Hi Gilles,

A 60 minute 1080p video in Vegas Pro 13, rendered to 720p29.970fps using the MainConcept AVC template VBR 16,000,000 max 8,000,000 avg, single pass yielded a 4.1 gig file. The size is going to vary dependent on the content both video and audio, as well as, the codec used.

I agree with Mike, using Handbrake is going to provide a better quality, smaller file size and faster render times.

If you are not familiar with FrameServing, you may want to do a search on Vegas2Handbrake. Full instructions are available on the net and everything you need is free to download and setup. Once you have installed the file and the script setup, it will send your project from Vegas to Handbrake via FrameServing using only a couple mouse clicks, and Handbrake will do the rendering for you.

Also a Google search will provide several file size calculators for mp4 files, all of which that I have tried were way off!!

Hope this helps.


Best Regards.....George

I'm not sure that reformatting a usb stick to NTFS is a good idea. Even if it does overcome the 2gb file limit. My understanding is that they are FAT so they can be read by Windows, Apple & Linux as Apple cannot read NTFS. But maybe things have changed. Also my three year old Panasonic TV will (according to the User Guide) only read FAT16 and FAT32 sticks.

Eric, it's my understanding that Apple can read from but not write to NTFS formatted devices.
I wasn't aware of the TV set limitation so that may be a concern. Gilles didn't say if this was a requirement or not so the decision is his.
Pretty sure that Handbrake can get the file to under 2 gigs. Not sure how good the quality will be though 🤐

Thanks Mike,
Yes, this will need to be read by TVs as well. SO Thanks Eric for the heads up on that one.

I followed the handbrake links Mike and it seems like a lot of work/time to get it setup. I'll see if I can stick with the core SVP12 features/offerings.

I'll do a test render this morning and see what I get. I don't yet have all the music for this documentary but I doubt this will increase the file size by much.

To expand on George's comment, the author of Handbrake posted the link here just the other day. Here's the relevant post that you need.

1. I use Vegasaur's video for YouTube version 1.4 extension. It's free
2. I got approximately 3.6 GB for a 1 hour finished project at 1080 using Vegasaur. 720p would be smaller. My source was 1920x1080 50i PAL. You can experiment with different quality settings of lower, normal (the default), higher or highest.
3. Yes
4. Probably is, but I don't know how ☺

I would do a test edit and render to confirm.

Thanks for this Nigel.

I will definitely try the extension you mentioned. Downloading it now ☺

On your 1 hour 1080 video, which bitrate(s) did you use to get it to 3.6 GB?

[Gilles Gagnon] "On your 1 hour 1080 video, which bitrate(s) did you use to get it to 3.6 GB?"

I let the plug-in decide. I used the 'normal' setting. When I look at the file properties, it is 7855 kbps. Other files I produced for other work have similar data rates.

I think the reason people struggle to tell you some specific number is because compression varies due to motion and changes in the video work. Low motion will compress better, high motion will need more bit rate and increase the file size. Only testing will give you what you want to know.

Generally for 720p h264 distribution, you do not need more than 10Mbs. YouTube streams at 6Mbs. Create new profile from an internet profile, and adjust the bit rate to roughly match 6-10Mbs. Then do some testing on your own.

Here are Google's settings for the various video sizes using h.264.

Thanks Aaron for this info. Yes, I agree that size will depend on the variations of the visual.

You provided good info here.

For everyone on this thread, I dis some testing given the many suggestions here and I'm all set. A 4 GB stick will work at a birate which will provide good quality (6-10 as Aaron mentioned or even using other suggestions such as the Vegasaurus util. The latter produced a 2.6 GB file.

Thanks to everyone who contributed here. I am very grateful and very much appreciate the help..
Cheers,

Gilles
