The long render times out of PPro do not sound right to me, I belive that the encoder is exactly the same for PPro and Encore therefore, it should be close.

If you have a lot of effects and layers etc, and render to a DV avi, it may just take the rendered temp files and just assemble them and output them, this would be very fast if recompress is not checked, also if are long parts w/o effects or transitions so it is just taking the original file, rendering what is needed for trans/effects/layer and spitting it out to the new .avi. If making an MPEG, it has to (re)render each frame…just a thought.

The issue to me is two fold, first rendering out an .avi (at anywhere from DV res to uncompressed) creates a large intermediate file, your final output will be MPEG 2, so why not render the smaller file out of the editor and not have to deal with the extra file.

Second, if you compress it to an .avi (with DV compression) – then to MPEG 2, you are double compressing and this can cause artifacts. For many, the artifacts are not an issue, but computer graphics break up more than video. I you lay graphics over video in PPro or mix other media like uncompressed video or 2:1 MJPEG, when you render the MPEG from the Adobe Encoder, it only compresses the uncompressed stuff one time, not DV then MPEG 2.

my two cents

Try to go to JVC’s page for the cam and click Video Clips, here’s a link.

Also, you might have to change the bitrates to make it smaller if it’s still too big. You may also have to turn the quality down a little, maybe 4.5 or so. It’s always a balancing act between the file size, quality and bitrate.

Zazi,

You might have figured this out already, but you need to compress the file more.

Use the preset just below the CBR preset, it is a 4×3 High Quality VBR with 5.1 surround. You need to change the Audio to PCM or better yet, mpeg to save more space (Don’t use the SurCode). Note when you change any parameter, you will make a Custom preset that you will have to name. Next select the video and you should see three sliders under Bitrate settings. VBR is variable bit rate, meaning it will put less compression where needed for quality (higer bitrate) and more compression where it can use more (lower bitrate). Turn the Max bitrate down from 9 to 7 or so. You might also turn the target down to 6 or 6.5.

Note also that the max bitrate for MPEG2 is 9mb/s or so and you really don’t want to get that high, it could cause problems with the DVD. The 2 pass VBR will go through the movie once to analyze it then the second time, it will encode it. This will take twice as long as CBR. I have not done single pass VBR, but assume it is better than CBR but the issue comes down to motion vectors and if there are parts of the video that go from pretty static to lots of movement, it may break up more with a single pass.

You might be able to re-compress it in Encore, but you would be doing a dual encoding and the artifacts will be very noticable. In addition, it is more difficult to find the encoding options in Encore.

Sorry, but it will take a long time to do. Probably too late for you, but hope this helps.

Alternately, if you have ALL your media in one folder, you can just reconnect one file when it launches and it should find all the rest. If you have media spread all over the drive in subfolders, you will have to relink one for each folder. The best thing to do is rename the drive letter, but if for some reason that is difficult (say you move to another computer that has that drive letter already assigned to an internal CD or DVD), then the relinking should fix it. You have to relink when it is opening, I believe, for it to find them automatically.

MPEG 2 was designed for output/distribution while DV is designed to be edited. The Handycams that record to DVD/MPEG are really consumer oriented to shoot and pop into a DVD to watch with no editing like home movies.

Theoretically, the MPEG can (and does often times) look better than DV, but if you look at the wiki link I have below, you will see that MPEG2 doesn’t have an actual frame at each frame whereas DV does.

What do you mean about the audio? Do you want it to work with broken out pairs by default not by jerking with the splitting the track?

Here’s the doc from Adobe, they have the link to the update in it.

Good luck

For uncompressed QT, select QT then none for compressor (like the .avi) not TIFF.

You need to make MPEG 2 for the DVD, so you should export it out of PPro with the Adobe Media Encoder. Select the MPEG2-DVD presets and start with the “NTSC DV 4×3 High Quality 7Mb VBR 2 Pass SurCode for Dolby Digital 5.1” preset. You get three free encodes with the SurCode encoder, so before you render this, switch to MPEG or PCM audio or if you are doing surround, you probably need to purchase the 5.1 encoder. The encoder will make the .m2v and a corresponding .wav or .mpa depending on which you select. Note, the VBR will “render” the file one time then it does it again. The first time, it is just looking at the file to decide where to vary the bitrate (hence the name Variable Bit Rate). So this process takes longer. If you are not concerned with saving space, you can use the CBR preset which is above the VBR preset.

If you render an .avi with DV compression out of PPro and import it into your DVD software to encode to MPEG2, you are double compressing and it will degrade quality.

If you render uncompressed .avi or .mov and import into DVD software and encode to MPEG2, you have a huge intermediate file to deal with.

If you plan it out properly, encoding the MPEG 2 out of PPro is the most logical thing to do for most situations.

For example: you have a majority of video that is DV25 and put some uncompressed graphics over the top, either supers or CG stuff or whatever. When you render to DV, you get nasty compression chunks and artifacts around the edges of the text or in gradients etc.. You could retain the quality and render out of PPRO as uncompressed .avi or .mov, but that again is a huge file and the DV content does not benefit AND you still have to compress it to MPEG2. The graphics do look good, but the file is hard to work with. If you render to MPEG2 as I specify above you don’t render to DV then MPEG2 (no concatenation from dual compression) and you have a decent sized file.

Note there is a bug with Hyperthreading and the Adobe Media Encoder, there is a patch from MainConcept to fix it.

In the Capture window (F5) hit the logging tab and at the very bottom in the capture area it says: Handles: 0 frames. Just change that to the correct amount of frames you want as handles then do the batch capture. I think this is NOT stored as metadata, rather it looks at this number each time you batch capture, so if you change it after logging, it will use the number when you actually do the batch. I have not done it in a while, so you should test this out.
