In defense of Tim, we have been struggling with downconverting ProRes 1080i material letterbox. Almost looks like a single field. On playback from the timeline the output looks clean…as soon as we edit to tape to a 5100a DVCAM it gets ratty at any diagonal lines in the footage. DVCProHD has been a better codec overall with less “surprises”, but so far we have not had the degree of reliability and stability that we have experienced with our SD Aurora Pipe systems. Just oddball issues along the way in a perfectly configured system.
Most of what we have seen was with either 10-bit or 8-bit proRes material in 1080i 24p and 720 60p.
We have troubleshooted the heck out of it and Kona will be getting a call tomorrow, but we wanted to check all possibilities…it’s very befuddling.
Regardless what you other guys say, Tim has an issue and Kona has somewhat admitted to a letterbox downconvert issue.

This has been my all time favorite portable drive for more than 5 years. That’s a long time loving one storage product!

I’ll have to check. I was sure it was a pre 2008 and we have it in the 3rd slot…second from the top. But if it is a 2008 then we ShOULD put it in the 3rd from the top slot. More testing on Monday.

Thanks Jeremy. Yes to everything but the NDD driver. We tried that before and it did not solve it. I believe we still have the 5.1. If so I might try going back to the 5.1 NDD.

Do you have a KONA card? Here’s our trick. Get a cable that takes two BNC and sends it to an S-Video connector on the other end. Now run the RCS outputs from the breakout box and the two bnc’s that make up the S-Video signal to the front of a DVD recorder. YOu can choose, with the Kona 3, how to down convert the signal. Letterbox, crop, anamorphic.
Since you are using FTP, set up the recorder to a setting that will give you 3 hours on a disc. this will make pretty small files per minute of video but still look good. I use this method for a quick and dirty SD MPEG encode. Also, you will get AC3 audio with that, if you need it.
Now, using MPEG Streamclip, simply demux the Video VOB files to an MPEG-2 file. You can mark in and outs to extract only parts of the clip to make shorter ones.
I suppose this would work best with short clips, rather than hours of footage, but if you are looking to send hours of MPEG-2 over FTP good luck. MPEG-1 would be better.
BTW, if you set your recorder to the 4-6 hour setting it actually creates MPEG-1 clips, at least on my Sony recorder.

Just lurking here to see what the flow is for Blu Ray in Vegas. I do know that in FCP if you try to export straight to DVDSP you can run into snags. If you export the clip as self contained or Reerence, encode in your encoding app, then bring that into the authoring software it almost always works.
Its always about workflow…sometimes the shortest path isn’t the most reliable.

Glad someone posted this. This is uber annoying. It has bugged me for quite a while but I just lived with it, along with all the other little things in our favorite “Pro” app.
Feeling grumpy,

A two hour sequence is barely going to fit on a standard DVD. You might end up waiting a couple hours for it to encode and end up with files too big to burn. Compressor would at least let you adjust your bitrate to ensure it would fit on the DVD.
Do you need to output the sequence to tape anyway…like an HDV master of the program? Since you have to do that anyway why not just upload the full clip as DV and encode that. Then you have a DV version. Not the most efficient, and only if you would normally output an HDV master.
In these long programs we are always looking for a quick method. It’s a LONG sequence. Any route is going to take a while. But if the one you choose doesn’t work, you have wasted that time. I like to pick the one that will certainly work, even if it might mean a longer encode or a bit of waiting.

Thanks Ken….this sort of confirms that HDV really only wants to travel over a firewire cable. Not too surprising, and in fact, Sony has probably repackaged the DSR 1500 DVCAM deck to allow it to playback HDV thru an HDSDI output, but is basically the same recorder.
I assume native RS422 control as well, component inputs and XLR?
Woe is the HDV format!

If you’re keeping score, David suggested that it might not even be possible, nor would I want to.
Here’s why he’s wrong.
An editor owns a Sony HDV camcorder. Shoots and edits in HDV…hey it’s his camera, his choice. he has a friend in another city who has a DVCProHD camera. He is available to shoot a once in a lifetime event, so the guy hires him. He approaches me to see if I can dub the DVCProHD to HDV tape.
I bite.
Here;s what I did.
Digitize two 30 minute DVCProHD tapes via 1200A deck and Kona 3 to 1080 60i DVCProHD.
Export Ref clips of the two tapes and import into compressor. Apply the HDV 1080i 60i preset and cook them. Each clip takes a little under an hour to transcode. (Quad Core Intel – 3.0 ghz)
Import those into FCP and set up an easy setup for HDV 1080i 60i. Hook the firewire from the MacPro to a Sony M25U deck.
Hit print to tape. Wait about 5 minutes while FCP analyzes the HDV stream to make sure it checks out…Print to tape begins.
Actually the transcoded HDV clips hold up very well to the source footage. No apparent gamma shifting and other than MPEG compression blocks, looks very good.
So, 30 minutes to upload each tape, 1 hour to transcode each clip and 30 minutes back out to tape. A straight dub would have taken 30 minutes per tape anyway, so if I figure about 4 times the running time of the footage I should be pretty close to calculating how much time it will take the next time.
And I’ll bet there will be a next time.
So there, David!
