A rendering error i dont understand

[Thomas Berg]

I too would like to know what to use to convert to a high quality H.264!

[James Round]

Try “Sorenson Squeeze” though im not too sure about it..

I think I found the answer with the error/ H.264 issue people. If you do you what the comments say for each setting (e.g. for H.264 – 720×480 on the stretch settings) and then click the aspect ratio checkbox off it should work. Well, I am rendering it now and it seems to be working – No more ‘AEGP Plugin Media IO Plugin: There is a mismatch between Output Module settings and Transcode Setting’ errors occurring.

Thank you so much , your tutorials are great, but your advice is greater, I had tried to render this project 5 times in 5 different ways and kept getting the same error. I’m so glad your at the top of google. LINX

Ok, it samed to work didn’t get the error, but when i tried view it, it only rendered haft of the footage out. So I started over. This is my first project on this mac so I’ll need a little help her.

I’m using H264 footage 720 x 1280 from my iphone first off. I can render QT movie fine, but the file size is to big big. I did as you suggested and checked the stretch box and changed out mode to H264 and I’m still getting the error.
Thanks for any help you can give

I was getting this same error when ever I tried to render out my 1280×720 comp in h.264. No matter what I tried the same error would pop up. Went over and looked at setting Vimeo recommends for h.264 and they suggest setting the level at 3.1+ for anything 720 HD and 4.2+ for anything 1080 HD. I tried this and it worked – I was finally able to output to h.264.

i just tried jason schoenfeld’s suggestion of using the 3.1 profile in ae to convert a prores 1280×720 29.97 fps quicktime into the same size h264. it worked beautifully without the error message that was driving me crazy when i tried to do it with the 3.0 profile. i uploaded it and it looks great and is automatically available in several resolutions on youtube.

i don’t get dave laronde’s criticism of after effects rendering. i’ve been using it for years and think it works fine. it would be more helpful if he would specify his workflow and why it’s better. what’s the best way to create h264 files? i’ve played around with apple compressor and qt player 7 exports but i was unable to get proper results.

i wish i could find a good tutorial that explains mpeg4/h264 profiles. i tried the wikipedia entry but i still don’t get it. wasn’t the idea of profiles to make this stuff easier?

thanks jason. the cow community has once again saved my bacon.

It’s funny, I always find this thread when some version of this problem consists (and I always forget and stumble on this thread).

I have a new puzzle. I’m trying to convert the AVI file to an another so I can successfully playback the file on my macbook. But after following the workaround, or simply choosing to export to a .mov file, the video is all black frame, with none of the visuals that should be in the video.

Any ideas?
