Question

MTS files (AVCHD) in After Effects - supported?

I have a Panasonic HMC 151 camera, clips saved as MTS.

I can add them to an After Effects comp, and I can see the individual frames, so far so good. When playing back however, the movie hops back and forth and the motion and progress is funny.

So - what is this?

    I am very impressed with Pavtube MTS Converter. I've had good results converting the .mts files to .mov, with the settings h.264, 1200, 1280*720, 25fps, aac. The files look good on my Mac running Adobe Premiere, edit easily, and convert well to DVD format. Pavtube will also turn out super 'lossless raw video' files, but these are so huge my mac can't cope.

    FWIW, I have upgraded After Effects to CS 5, and CS 5 has no problem with my Panasonic MTS (AVCHD) files. This is a big leap forward, although it wold have been good if Adobe supplied updates for CS4 fixing this. Anyhow, the new rotobrush justifies the upgrade, so all in all I recommend AE CS5.

    MTS files (AVCHD) in After Effects - supported?

    Generally yes, but obviously not all of its flavors. Some cameras do not flag their streams correctly or add additional, non-standardized data that confuses AE. For those formats unfortunately only converting them before bringing into AE guarantees correct results. If you can provide a short clip (~30 MB, 5-10 secs.) we can investigate in the hopes that at latest for CS5 those formats are supported correctly.

    I have a 30 seconds long clip. I make a new comp in AE and add this clip to the timeline.

    I set a working area of about 8 seconds. The first 5 seconds playback is perfect, then it starts to hop back and forth. When sliding the work area on the timeline, I observe the same phenomenon. First 5 seconds fine, the rest just a mess.

    This is a real real disappointment. AVCHD is here to stay. In Sony Vegas, my favorite NLE, I edit AVCHD right off the camera. In Cs4 Production Premium, which costs 7 times more, I cannot edit AVCHD. I really do not want to wait for CS 5 to be able to use MTS files directly. I hope Adobe will issue an update to fix this. Or at least come up with some sort of a workaround or utility that will fix the problem.

    The images look just great as they are. Fix this issue please, I do not want to transcode and introduce more artifacts than I already have in the compressed AVCHD files, I want to use my MTS files as is. In case you wish, I can supply a file. How do I do this?

    Anyhows - I had thought Adobe already have access to such files, this camera is all over now, very popular.

    There's no need to provide more examples.

    Adobe is aware of this issue and has test files from that camera already. And is working with the provider of the AVHCD decoding technology, since that module was developed before this camera was introduced. For most other cameras, AVCHD decoding is working well.

    As I said, I am afraid I can't give a time frame now.

    If you convert the AVCHD files to a lossless codec (such as Quicktime PNG), you won't introduce further compression artifacts. For AVI, there are a number of free lossless codecs out there that you can download.

    I know that having to convert source files is inconvenient, even if a lot of users choose to do that anyway, This is just a workaround, not a solution. Sorry for the inconvenience.

    Yes, AVCHD is supported natively in AE CS 4.

    However, as you noted, there are some decoding issues with footage from certain, newer models. The specific camera you mention keeps being mentioned all the time. Bummer, I know.

    The workaround for now is converting the footage to another format. If you google for "AVCHD converter", you'll find a ton of applications that do just that.

    Many users will tell you that converting temporally compressed footage (AVCHD, HDV, etc) to a spatially compressed format (or uncompressed, if possible) is always recommended for performance reasons. Agreed, but at the same time, a supported format is a supported format. Unfortunately, file-based formats are a bit of a moving target, as they are more likely to bend the specs as new models are released. Adobe is working with all parts involved. I can't mention a time frame, though.
