Adobe Media Encoder Abilites
I couldn't find a media encoder forum, but figured this was related, sorry about that.
I'm attempting to convert multiple files from hd resolution to windows media format in mpeg 4 v3, this is working fine so far with media encoder, had lots of problems with after effects and rendering errors.
Unfortunately, some of our videos are upside down and I want to mirror them and convert them in one step with media encoder? Is this possible, is there some kind of filter addon we can purchase?
I dont want to use after effects because of all the skipping videos it has produced.
Thanks for any help.
It sounds like you have two issues going on:
1) concerning the types of video files you've used in AE in the past, and
2) concerning the proper way to create media files when working in AE. These are both VERY common problems, and here are the answers in order:
Dave's Stock Answer #1:
If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, AVCHD, mp4, mts, m2t, H.261 or H.264 -- you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.
I'm a Mac guy, so I like to convert to Quicktime movies in the Animation or PNG codecs; both are lossless. I'll use Apple's Compressor, Adobe Media Encoder or Quicktime Pro to do it.
Dave's Stock Answer #3:
Don't use AE to compress files for final delivery. The various compressors are there only to make quick 'n dirty files showing a project's progress to producers, clients, the kids, etc. AE is incapable of doing multipass encoding, a crucial feature that greatly improves the image quality of H.264 and MPEG-type files in particular.
Render a high-quality file from AE, and use a different application to do the compression. Popular ones are Adobe Media Encoder, Sorenson Squeeze and Apple's Compressor, which comes bundled with Final Cut Suite. Even compressing in Quicktime Pro is better than compressing in AE.
Making good-looking compressed files is almost as much an art as it is a science. It is NOT straightforward at all. I recommend asking a few questions at the COW's Compression Techniques forum.
