Problems with Intelligent SVRT

Hello

I am having some problems with Intelligent SVRT recognising the footage from my Sanyo Xacti VPC-SH1 and therefore save time on rendering

The footage is H.264 AVC MP4

When I go to produce and press Intelligent SVRT the box opens and it suggests a profile which I have created under the MP4 tab, however the writing in the box is all in red and the Apply button is not highlighted so I have to add this manually.

The SVRT button at the bottom of the screen is also greyed out when I use the suggested profile settings

Using the Show SVRT Track option under the Edit heading all the videos are highlighted red as well and this is the raw footage with no transitions or alterations.

have made sure the TV aspect match and also have tried the "Allow SVRT on single IDR H.264 video" option ticked and unticked

I have quite a few large files so using the SVRT option will be very beneficial

I've included a sample clip I have just recorded.

Any pointers or advice will be most appreciated

From what I could tell, your clip is basically 29.97 fps progressive, even though PowerDirector shows the properties as 59.94 fps interlaced. Do you have your camera set to a 30P setting? What make and model camera did you use?

You need to tell PowerDirector that your clip is Progressive. You do that on the timeline: right-click on the clip and select from the pop-up menu "Select Clip Attributes" > "Set TV Format," and set to "This video clip is progressive."

In User Preferences, set TV Format to "30," and set Use Drop Frame Timecode to "Yes"

To create a custom profile for producing MPEG-4 AVC:

frame rate: 29.97
frame type: Progressive
profile type: Main profile
entropy encoding: CAVLC
bitrate: 17010 (for that specific clip) (must be same or higher as the actual bitrates of the clips)

On the Audio tab, change audio compression rate to 256 kbps. (not necessary for SVRT).

Turn off "Enable preview during production."

Now SVRT should be available. Intelligent SVRT won't detect this custom profile.

A 6-second clip is too short for SVRT to actually kick in, so recompression will occur. There is a minimum production length of 60 seconds before SVRT actually is used where there is no recompression of video. These are the rules that you will find in Cyberlink PowerDirector Help:

Intelligent SVRT can be applied to video clips in the MPEG-1, MPEG-2, H.264 and DV-AVI (Type I) formats. In the following conditions, clips (or portions of clips) do not require rendering during production, and SVRT can therefore be applied:

· The frame rate, frame size, and file format are the same as those of the destination production profile.

· The bitrate is similar to that of the destination production profile.

· The TV format is the same as that of the destination production profile. For more information, see Setting TV (Video Clip Interlacing) Format.

If all of the above conditions are met, SVRT can be used. Any clips that do not meet the above criteria are fully rendered without SVRT.

In the following conditions, clips (or portions of clips) must be rendered during production, and SVRT can therefore not be applied:

· Adding a title or transition effect

· Modifying the color of a video clip

· Merging two video clips (clips within 2 seconds before or after the merged clips will be rendered)

· Splitting a video clip (clips within 2 seconds before or after the split will be rendered)

· Trimming a video clip (clips within 2 seconds before or after the trimmed clip will be rendered)

· If the total duration of the production is less than one minute and any portion of the video requires rendering, the entire production will be rendered for efficiency reasons.

Xerox many thanks for the reply

My camera is a Sanyo Xacti VPC-SH1 and the setting I used for the test capture and all my others is on Full HD 1920 x 1080 60 field/s (as taken from the camera settings)

I have used Gspot and MediaInfo and both are saying that my clips are 59.940 fps, im not sure how I can tell if it is progressive or not although I always did think that this camera captured in full 1080p

I have tried your suggestions and various options on a clip that lasted 2mins with no additions or transitions and followed all the rules for svrt but still it is not kicking in

Hi Paul1970

I may not have the answer but can you check to see if it is available for the clip inserted on the timeline?

It has been a source of irritation to me for several releases.

I can trigger, and apparently use??, SVRT on my raw Sanyo VPC or Sanyo HD clips using a custom profile, which never appears in the "intelligent??? SVRT" window as a choice to pick. Such clips are sometimes produced successfully, but sometimes not - in that they may not play in any player - and they rarely trigger the .mp4 icon in any file window.

Even if they are produced and play OK, bringing the produced clip back into PD and producing again will not trigger SVRT, even when choosing the original custom profile that triggered SVRT in the first place.

However, if the original files are left on the timeline and the produced file placed after them then SVRT is "triggered" but may not actually be implemented.

Needless to say I have, apart from some odd testing, abandoned SVRT for my raw clips.

Dafydd did work on this some time ago as well and may have more to offer.

Sadly
Adrian

Thanks Dave tried that and it shows the SVRT custom profile that I created to match the Intelligent SVRT one however it always shows red and that all the file needs rendering.

vn800rider thanks for the info its a shame that SVRT cannot be used, especially as it was one of the selling points for me. Im going to carry on trying to get a result, but sad to say I think I will end up being in the same situation as yourself

The manual for that camera shows 1920x1080 at 59.94 fields per second interlaced, which in PowerDirector equates to 29.97 frames per second (or 59.94 fields per second) interlaced; you need to select 29.97 fps interlaced in the Produce profiles. The camera also has 1920x1080 30p, which is 29.97 frames per second progressive. See page 63 of the PDF manual: http://us.sanyo.com/dynamic/product/Downloads/VPC-SH1_OM_English-36834105.pdf

Are you saying that the SVRT option was enabled, but SVRT wasn't actually used? or are you saying that the SVRT option was still greyed out?

After MediaInfo launches, I go to the menu and select Debug > Advanced Mode, then View > Text. You'll have to scroll down a ways before you see that it shows "interlaced."

Hi,

Following what Adrian and Xerox have written.
Adrian, I've had differing results in a W8 setup. Not for discussion here but there is a n issue for mp4 SVRT users.

Xerox, you've ponted the way for a profile to be generated.

SVRT Track View fails to display the use of the profile (below) but it uses it in Produce.

Guys thanks you so much, I have used the settings that Xerox suggested and the SVRT is now working.

Xerox thanks so much for the info re camera settings ill change capture in future to the progressive setting, school boy error should always read the manual lol

Great Forum, and great product

60i is actually better than 30p. Where there is motion, the 60i will be clearer. With 60i, you have 60 fields per second, but with 30p you have only 30 fields per second.
