Ok, this sounds the answer!
Well, so I have to transcode the uncompressed clip inside the authoring software, not BEFORE.
I solved the problem by compressing before to import the clip in Encore: I have an uncompressed 720×576 “squeezed horizontaly” clip and I tell compressor to make an MPEG2 at still 720×576 but with a display aspect ratio of 16:9.. doing so, the importeed clip looks ok in Encore.
Anyway, my last question is.. do you think it’s better to FIRST transcode the clip and then import it in the authoring software or import the uncompressed and transcode later?

Thanks Heath for your reply,

I looked for the “right click option” to conform the clip to the 16:9 aspect ratio, I found it but it’s disabled… I can see it in the option menu, but I’m not able to select it..
Any ideas??

Hello Floh,
I solved the issue of the “strobe effect” in the HDMI capture scheme: anyway, it stills remain when I downconvert from HDV to DV and I really don’t know how to solve it.
Maybe you were right: my camcorder and FCP don’t work well together in the downconversion workflow.
The last thing I can do it’s to downcovert through software the 1920×1080 50i ProRes clip, captured through HDMI: anyway, I’ve to pass from square pixels to non square pixels and downscaling to PAL 720×576 (PAR 1,42): do you thing Compressor is a good choice for this?

Hello,
it’s a known issue.. some camcorders have this problem.
I think it’s cause of the camera, not of the compression: I’ve a Sony V1 and it’s affected by the same problem.. it could be interesting to discuss about this argument.
Any time there’s a photographer near me when I’m shooting, if he take pictures with flash, in my tapes I see a blank frame ( all blank)… it’s horrible!
Maybe someone can help us.

Hi, I’m sure you see a “strobe” effect, no a “flicker” effect: it’s because you don’t set the field dominance correctly.
I’m in the PAL land too, so the fields dominance must be set to “Top field first” or “Upper”.
For graphics, try to deinterlace all in Photoshop before to import in your project.

Hi, I’m sure you see a “strobe” effect, no a “flicker” effect: it’s because you don’t set the field dominance correctly.

In your source material is NTSC, I think you have to select “Bottom field first” or “Lower” for field rendering (I’m in the PAL land, here it’s the opposite: “Top field first” or “Upper”).

If your source is progressive: well, you can encode it as progressive, but your DVD player must be able to read progressive source. Anyway, it’s better to remain in the interlaced world and you have to “interlace” your video.

Hi, in AE I always export in uncompressed or high bit rate codec. Now, I use the last Apple ProRes Codec, but before I used to export in Animation codec: ProRes has the same quality of Animation but at lower bit rates (smaller exported files)
Then, I use Compressor (but you can use Squeeze or something like that) to obtain the MPEG2 for your DVDs.

[marguu] “I’m authoring my first dvd. I know this has been addressed before, but I can’t find the exact answer I need. My program is very large, probably 3+ hours of video. I will be outputting to a dual layer dvd. In calculating the bit rate, do I calculate the video and audio separately? ie; if I have 60 minutes of video tied to audio, do I calculate 120 minutes? Or 60? I know I need to calculate separate audio (like music) in addition to the A/V.”

Hi, of ourse you’ve to calculate the disk space needed to record audio and video (and graphics if there is, for example a motion menu or something like that): if you work on a MAc, download this widget to calculate bit rate/disk space.

[marguu] “Also, I am editing on FCP, should I import through compressor? Or a by reference movie? I’ve done small tests as a by reference movie and it looks fine, but I am only testing in 10 minute segments.”

You have to EXPORT from FCP to Compressor directly, not using QuickTime export: if your target is a DVD, you need to encode your clip in MPEG2.. so, do it exporting to Compressor directly.

[marguu] “One more question. Can I apply a different bit rate to different segments? Like give a higher bit rate to the feature and lower on the extras?”

Yes, you can.

[Floah] “Resize like in from HD to SD, or resize like in from 4:3 to 16:9?”

I mean: capture HDV from FireWire in FCP (and see if the strobe goes away), than resize the clip to a SD compatible format (better if 16:9) and, finally, import, edid and export it in Producer.
I don’t know how to make my shooted tapes good looking, I’m thinking all the possible ways…

Alessio

[Alessio Gemma]

Yeah, I trust in Media 100!

Last thing: if I capture in HDV and I solve the issue of the strobe effect, how can I resize the clip corretly to import in Producer?
Maybe you’ve a good workflow for me (or maybe you already did it)… I really hope the last one! 😉
