Premiere Pro and Windows Movie Maker

Hi,

I use Nebula DigiTV to record TV programmes, and your software seems to be great at opening the files and chopping out the bits I don't want.

However, I wanted to convert a chopped file into a compressed Windows Media Video file so I could show a clip of something to someone at work without a lengthy download, so I tried importing the MPG I had saved from VideoReDo into the two packages I use to create WMV files.

Windows Movie Maker rejected the file outright, saying I did not have the correct codec on my machine to play it, which is not true as I have PowerDVD installed so can play MPEGs.

Adobe Premiere Pro (v1.5) imported the file OK and appeared to be OK when 'scrubbing' along the timeline, but when rendered or output the video raced ahead of the audio (very fast video, normal pace audio).

Anyone know why this is? Any better suggestions of how to get my edited MPG from VideoReDo into WMV format?

Can't say for sure. I just loaded a bunch of edited clips into MovieMaker without problem. Don't have Premiere so I can't test that. Do you have the word alignment option in Tools>Options>Advanced Stream turned on? That's the option needed to create DigiTV player compatible streams. Perhaps that's affecting something.

Also have you tried loading the edited videos into the Windows Media Player? If they have problems playing there then you won't be able to edit them in MovieMaker.

Another way to get them into WMV is to simply open up the WMV encoder, import your MPG file and convert it the WMV. No external editor required.

Thanks for the tips, I will try those when I'm home later.

I'm rather going off my own topic here but can I just clarify that I am doing the right thing to get a good output file? I am opening the file recorded with DigiTV - i.e. the direct recording of the broadcast MPEG stream - in your software. Is this right or am I supposed to use ProjectX or some such product to 'fix' the stream first? Your software plays back the unaltered DigiTV recording without any problem so I had thought I didn't need to do anything to it first but now I've started thinking, hmm, should I have done?!

Thanks very much!

You can open and edit the DigiTV stream directly into VideoReDo. No other conversion programs are necessary. However, the DigiTV streams have a somewhat unique byte alignment requirement (as mentioned above). Their players requires this alignment to avoid pixelation, but other players do not. Therefore, you might want to turn off the Word Align option if its currently on.

Thanks very much for the explanation.

The file I output from VideoReDo last night is very pixellated when played in DigiTV, sometimes even crashing it completely, so I suspect I already have that option off. Which doesn't explain why my files won't open in Movie Maker etc, so I will have to check my settings later and let you know!

Thanks again.

Just checked and I don't have that option enabled so I guess something else is amiss. I don't have time to do any further experimentation now but I can tell you that Windows Media Player opens the MPEG but then plays it back incredibly jerkily, extremely slowly, and probably not in sync (but it's hard to tell due to the speed and jerkiness!).

Oh, the MPEG is on my web server as it happens, so if you want to grab it you're welcome to:

http://home.paulspeller.co.uk/videoredo/edited-output.mpg (12MB)

(The WMV which Premiere output is there too at http://home.paulspeller.co.uk/videoredo/edited-output.wmv by the way)

Thanks!

I'll check your streams out. One more thing, make sure that the Movie Factory compatability option on the Tools>Advanced Stream Page is OFF. This might affect things, but since you're not using MF anyway, be sure its OFF.

Downloaded your .mpg and it imported fine into MovieMaker. Outputted to WMV without difficulty. So, my guess its the decoder, or lack thereof. Why don't you try downloading the Elcard/Moonlight decoder. They have a free trial and its very, very good.

Hi again,

Thanks very much for the tip about Elecard - it's a fabulous codec. I can't believe it has existed for all this time - I can watch my Nebula recordings in WMP now for instance!

Unfortunately, though, it doesn't quite seem to solve the problem. Although the file that has been output from VideoReDo now plays back in full and without any video or sound problems, Windows Media Player thinks it is 6 seconds long, when it's actually 25. The progress bar races along to the end for the first six seconds, then stops at the end while the remaining 19 seconds play on happily. In other words if you ignore the time display and progress bar in WMP it appears that nothing is wrong. However, the result of this is that when I import it into Windows Movie Maker, it gets truncated and I only get the first six or seven seconds in my video. These first few seconds work without issue, but of course I want the whole video!

Thanks for all your help with this, it's much appreciated. To answer your previous post, I do indeed have the MF option turned off.

One last thing - when I export the video (which I have just done from scratch again to make sure I have been doing it all correctly), the results dialog thing has some red text at the top, "PTS underflow: 8". Is this bad (as red text tends to be!)?

I see what you mean, it happens with the short clip. Try this: When you save with VideoReDo lower the bitrate to 8MBps. To do this, click on the Options button in the lower right of the file save dialog. In the bitrate drop-down box set the bitrate to 8 Mbps. That fixed it on my system.

A few PTS underflow aren't bad, they indicate that momentarily the video bit rate exceeded the stream bitrate.

Interesting - changing the bitrate made it work in WMP, and show the correct duration (25s), but when I imported it into Movie Maker it still showed as the shorter duration and was truncated. Thanks for the pointer though.

(I'm a bit confused by the 'change bitrate' option, as the software doesn't re-encode the file so I couldn't see how it could change the bitrate, but I guess it does it in some other cunning way. Point me to read the manual on this one if you want, I'm sure it's documented there but I'm just going out so haven't time to look!)

Thanks!

Its not really changing the bit rate of the data, just the header which has the maximum bit rate. For DVB broadcasts, the max bit rate in the header is always 15 Mbps (Tools>Show program info). But, the actual bitrate of your video is 3.84Mbps (as reported by VideoReDo in the output dialog). This is typical, DVB broadcasters will lower the actual bitrate to pack more data into their allocated frequency spectrum.

When you save Movie Maker are you referring to MSoft's Windows Movie Maker? If so, I have no problems with it in that program, either the original or with the revised bit rates. Creates WMV that show the proper length (25s).
