Editing footage with an H.264 codec
on Feb 4, 2010 at 10:08:06 am

When editing on a sequence with an H.264 codec, dropped frames keep being reported during playback. I get the usual advice, including turning off 'Unlimited RT' (which I can't work out how to do in FCP7, although I don't think this is the problem). I have tried everything else Final Cut suggests, is it a problem that I can't help because they are compressed H.264 files I am editing with?

Any help much appreciated

I thought h 264 was a compression for output not an editing codec..

Right, you wom't find H264 in the list of the supported formats and codecs.
You may try to cut, but don't apply any kind of effect or motion change.
Better transcode to whatever other editing codec.

[Dominic Stabb] "When editing on a sequence with an H.264 codec, dropped frames keep being reported during playback."

I'm not surprised about that, and Brad Kopp is right: H.264 is NOT an editing codec, not one bit. You need to convert the footage to something that's more FCP-friendly, like ProRes. You can use Compressor for that job.

Hi there,

I've just read this post. I have a similar problem. I did converted
AVCHD into H.264 codec thanks to an ignorant friend who likes to show off she knows about video edition.

I don't know much myself about editing.

I need some help with this footage I have to edit with final cut pro 5. I was told to convert my AVCHD into apple intermediate codec. I understand that. Though I do not know which format to use. Mov-Mpeg 4?
Size? Right now I have this:

1280x720
mpeg 4
h.264 ACC

I obtained this files after transcoding with Emisoft converter of M2ts for mac.

When I imported this to final cut, I had to select the sequence settings to:

frame size: 1280x720
aspect ratio:HDTV 720p (16:9)
square
anamorphic not check
compression h.264


Obviously, i have been finally able to check by myself what the knowledgable guys said: that you can't edit with h.264. i can cut the sequence but it doesnt even allow me to do any simple edit.

I would really appreciate CLEAR ADVICE OF WHAT TO DO WITH THE H.264 files i already have. Should i convert this again to apple intermediate codec? which format should i use? i would like to be able to edit and keep good quality in order to export for internet and also for a dvd.

please, I need less 'showing off' and someone who can really explain things to help and not to confusing learners.

many thanks.
