ＡＶＩ→ＭＰ４　２ＰＡＳＳで動画が結合される？

akJBetas0.6.18とFFmpeg version SVN-r18607の環境にて、ＡＶＩファイルからニコニコ動画用に次の設定でＭＰ４を作ると、時間が2倍の動画ができます。
後半は音声なしで・・・。
２ＰＡＳＳの2回目を1回目に結合してるみたいな動作です。私だけでしょうか。
20回近くこんな状態で、ごくごくごくごく稀に（その20回で1回）ちゃんとした動画ができます（汗

（１）音声コミのＡＶＩファイルを用意
（２）ファイル拡張子ＭＰ４、h264、512×384、400ｋにチェック
（３）音声はaac 256k 44100 チャンネル２
（４）時間範囲を0:0:0変換時間を無指定またはＡＶＩファイルの時間を指定

1分23秒のＡＶＩファイルなんですが、変換時間に0:0:0・0:1:23としてできあがるのは
1分23秒まで正常に再生されたあと、画像だけがもう一回最初から再生される2分46秒の動画です。

JBetasインストールページの推奨FFmpegはh264非対応とのことで使用できませんでした。

ログ添付します。
