Nothing compares to uncompressed visual data, like a PSD file.
But in the real world it all comes down to a balance of size/quality.
High quality like uncompressed will be large file sizes (High number Bitrate). However there is a point of perceived High Quality – which is determined by the viewer.
A trained eye, like an editor, is not always the intended audience. Most things I see on TV are poorly compressed and I can’t imagine how it when to air looking like that. On the other hand my wife/brother/mother/non video friends don’t see the problems I do. Because I have a very critical and trained eye I am able to spot when something is 1 frame off, a lay person can happily watch something thats 5 frames out and not twig that something wrong.
As technicians we tend to forget about this simple principal – “who is the intended audience, will they notice…are they able to compare the uncompressed version to the export…and is it reasonable to make the bitrate so much higher for an ounce of quality….?”.
Keeping this in mind can save hours if not days of stress (hair) and time none of us will ever get back.
So if you think you truly believe the audience will look at your export and feel cheated on quality as something on its own (no comparison to original) then up the bitrate. Work in small sections at a time to find the happy medium settings for size Vs quality. If you work to a 10sec workarea export and multiply the file size by 6
10sec footage = # MB
# MB x 6 = 1 min of ## MB
1 min ## MB x total mins of project = Total Estimated Project Size.Keep in mind there are limits in File Size for DVDs/Dual Layer DVDs, BluRay Disc, and websites. People don’t what to spend time downloading video for a quality that will probably wash over them.
Just a quick word about web/mobile. Viewers want to watch. not download. They only need to see with enough clarity to understand what’s being shown and hear everything happening. The lowest bitrate possible that holds onto the “ability to communicate” is always the best methodology to apply to web/mobile based content.

I don’t think anyone has mentioned the version of Quicktime they are using. The latest ain’t always the greatest.

Umm. Yep. That’s a bug. It’s a known issue. Thankfully cs4 can follow file infrastructure so finding 1 item in a group will point the system to all files associated with that folder location.

It appears you have either deinterlaced or edited in an interlaced timeline and set export to progressive.
Did u edit in a custom or preset timeline?
Did u try to export a sample to compare with the maximum quality ticked in the hidden option. Of ame settings?
I have worked with multiple screen capture apps and not experienced your results. So this is not normal/expected behaviour.

It’s probably nit true 30p. I’d say like most prosumer gear it’s 30p embedded in 60i. So there is nothing wrong it’s correct technically. The “look” is 30p not actual 30 prgressive frames. So ppro sees the digital tags and tell u it’s 60i.

U can only export and expect an alpha onstaed of black of u export to an alpha friendly codec like animation QuickTime with millions colors +.
If it doesn’t allow for millions colors + (the + is the alpha) u get black.

I own a Z1p and can verify that u can’t shoot cf24 in pal mode cf25 is the only option available in pal mode. Cf24 is only available in the NTSC mode.
I don’t know the tech specs of your deck but u will need to switch to an NTSC playback and then capture in NTSC hdv as the cf24 is embedded in the 29.97 fps signal.
Either ur camera guy has no regard for the country he has shot in or doesn’t understand the limitaions of shooting in another format that’s not native to the country its being made for.
Try to capture with an NTSC hdv project.
Are u sure it’s cineframe24? U should be able to see it in the deck display settings somewhere.

It appears your clip is not dv but some other consumer camera recording.
1st try to make a new project. Goto file import and select the troubled ppro project file. Select entire project. It will import into a folder named the same as your trouble project. Open the folder and double click the seq file of ur trouble project. See if the new conforming has fixed the issue…
If that doesn’t fix it I suggest u convert the entire file to uncompressed avi or dv avi. U can dobthe conversion in either media encoder or a third party app.
Does the clip work in a new cs4 ppro project? If so export it there. Then open the old project and unlink (make offline) the problem file and relink it to the dv or uncompressed avi.
That should work.

If you are working on projects that are not newly build, I’d clean the media cache from the preferences and let the entire conforming, indexing process start again. It should only require to do it once. The only reason it may keep doing it is that there is a problem with them. Cleaning them out, rebooting your system should give CS4 a clean set to work with.
Let it finish doing the conforming, indexing before working. it takes longer when you work while its happening and it means the conforming not yet done can be corrupted if you try to use the file its currently conforming.
Let us know how this works out.

Are you trying to use the headphones after you’ve launched ppro?
The audio settings in preferences may need to be adjusted to go out to the headphones.
